"36" (=North) facing the 24H hand.
Point the hour hand (keeping the dial
level) in the direction of the sun and your
compass is activated.
B) In the southern hemisphere put the
"18" (=South) facing the 24H hand.
Point the hour hand (keeping the dial

SEASTRONG YACHT TIMER
1. IN THE NORTHERN HEMISPHERE
- Set the "S" (=South) on the rotating
compass bezel to the middle of the
arc between the "60" marker (=12
o'clock) and the hour hand.*
* in the AM period, set the "S" to the left
other functions
of the "60" marker (=12 o'clock) and
in the PM period to the right of the "60"
marker (=12 o'clock).
- While keeping the dial level, point the
hour hand in the direction of the sun.
- Now the compass is activated and
you can read the directions on the
rotating compass bezel. The triangle
at "60", the 90 marker, the "S" and
the 270 marker indicate North, East,
South and West, respectively.
EXAMPLE 1: It is 10 am in your area.

ANTI-
MAGNETISM
Magnetic fields can significantly impact
the precision of your watch. There are
many sources of magnetic fields, such
as mobile phones, iPads, computers,
loudspeakers, refrigerators and other
electronic devices. The more powerful
the magnetic field the higher the impact
on your watch. All Alpina watches
designated by "4", i.e. the "Alpiner 4",
are anti-magnetic. This means that they
have a minimal deviation when exposed
to a certain level of magnetic field.
Alpina "4" anti-magnetic watches conform
to the international ISO 764 standard
which defines the resistance of watches
to magnetic fields. According to ISO 764
a watch must resist exposition to a direct
current magnetic field of 4,800 A/m.
The watch must keep its accuracy to
± 30 seconds/day as measured before
the test in order to be recognised as a
magnetic-resistant watch.
